The Carmex Carbide Tiny Tool for Small Threading (UNJ MIL) is a precision cutting tool designed for small threading applications. Featuring a UNJ thread design for high-accuracy threads, this tool is crafted from premium BMK-grade carbide to deliver durable performance in miniature components. Its compact form accommodates tight spaces and it’s built with a 5 mm minimum diameter and 18 mm reach, plus left-hand threading, making it versatile for a wide range of machines and setups.

  • Small-diameter UNJ threading for tiny parts: Enables precise UNJ threads on miniature components, improving fit, function, and reliability in tight spaces.
  • BMK-grade carbide for durability: Premium carbide resists wear and maintains sharpness, delivering consistent cut life across multiple jobs.
  • Wide compatibility with left-hand threading: Designed to work with many machines and systems and supports left-hand UNJ threads for broader application coverage.

This tool helps you streamline your threading workflow by delivering accurate results where space is limited. Its durable carbide construction reduces downtime from tool wear, while the compact geometry enables efficient setups and repeatable performance across demanding small-part applications. With reliable UNJ threading and broad machine compatibility, you can expect consistent, high-quality threads that accelerate assembly and reduce rework.
